WSL analyzer works better then normal windows

[I-ABD-I]

The last few days i have been doing aoc and i noticed that the type inference on windows is "shitty" in respect to WSL
for example this code snippet

fn to_2d_array(input: &str) -> Vec<Vec<char>> {
    input
        .lines() // Split the string by '\n' into an iterator of &str
        .map(|line| line.chars().collect()) // Convert each line into a Vec<char>
        .collect() // Collect into a Vec<Vec<char>>
}

fn stage1(input: &str) -> i32 {
    let arr = to_2d_array(input);

    let mut count = 0;

    for (i, line) in arr.iter().enumerate() {
        for (j, c) in line.iter().enumerate() {  
        // ...
        }
    }
}

when viewing on VS Code running on windows, rust analyzer does not recognize the types for line and for c
but when i opened the same workspace on WSL suddenly it does know those same types. thats just one example i encountered.

---------------------------------------- ON WINDOWS ----------------------------------------

---------------------------------------- ON WSL ----------------------------------------

is there a fix for this, or is this just a bug?
